Abstract

A motion vector detector includes a motion vector computing circuit (9) for achieving a computation of a motion vector associated with an input image signal, an integrator circuit (11) for integrating the motion vector, a coring value decision circuit (12) for decid­ ing a coring value based on an output from the integrator circuit, and a coring circuit (10) of which a coring value is controlled by an output from the coring decision circuit and which accomplishes a coring operation on an output from the motion vector computing circuit.
